In a bag of red and yellow cookies the ratio of red cookies to yellow cookies is 4 : 5 if the bag contains 80 yellow cookies how many cookies are there

144 total cookies

Step-by-step explanation:

First, set up a proportion to find out how many red cookies there are. 4 over 5 is equal to x over 80. Cross-multiply and you will get 64 red cookies. This question is asking how many total cookies there are, so you would add the red and yellow cookies together. 64 plus 80 is 144 total cookies.

- 70

this is the answer for you hope it

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
